Description

Technical Field

[0001] This invention relates to the field of robotics, and in particular to a medical supply delivery robot with a sterile cabin self-disinfection function. Background Technology

[0002] With the development of robotics and intelligent technology, the application fields of robots are becoming wider and wider, effectively solving a variety of simple or complex work tasks, thereby improving work efficiency. In hospitals, robots are also gradually being used to replace manual labor in the distribution of medical devices and other supplies, thus completing the transfer and distribution of medical supplies.

[0003] A search revealed the Chinese patent "A Disinfection Device for a Delivery Robot Cabin" (CN216652925U), which includes a cabin, a power supply, an ultraviolet disinfection device, a liquid disinfection device, and a control device. The device is electrically connected to the power supply and controls the ultraviolet and liquid disinfection devices. It adds a UVC ultraviolet LED and an alcohol disinfection spray system to the traditional delivery box, utilizing the bactericidal properties of ultraviolet light and alcohol to effectively disinfect delivered items, reducing the harm caused by cross-infection. The system uses a reflector and a rolling rod through which the disinfectant can pass to disinfect the lower surface of the delivered items. However, this method has the following drawbacks in actual use: the disinfectant spray has a limited coverage effect and a short suspension time, leading to increased disinfectant usage and poor disinfection effect, prolonging the entire disinfection process. Furthermore, when items are picked up or placed after the cabin door is opened, the user's hands easily come into contact with the interior of the cabin, and external dust and bacteria can easily enter, increasing the burden of subsequent disinfection. Summary of the Invention

[0004] Therefore, it is necessary to provide a medical supply delivery robot with a sterile cabin self-disinfection function to address the problems of poor disinfection effect, prolonged disinfection operation time, and easy entry of bacteria into the cabin.

[0005] A medical supply delivery robot with a sterile cabin self-disinfection function includes a delivery cabin and a walking mechanism for driving its movement. Two delivery cabins are provided, each with two sets of atomizing nozzles inside. The robot also includes two disinfection mechanisms located inside the delivery cabins to enhance the disinfectant's permeability and suspension time. Each disinfection mechanism includes a rotatable conical column and a collar rotatably fitted onto its outer side. A set of cartridges is located on the outer side of the conical column, and a germicidal lamp strip is installed inside each cartridge. A set of flared grooves evenly distributed along the axis of the conical column is formed inside the collar. A set of baffles evenly distributed along the axis of the conical column is located on one side of the collar, with the baffles and flared grooves arranged alternately.

[0006] In one embodiment, the disinfection mechanism further includes two folded tubes, which are asymmetrically arranged, with the ends of the folded tubes inclined upwards and facing the collar.

[0007] In one embodiment, the delivery compartment has two fixed boxes symmetrically arranged along the axis of a conical column. The atomizing nozzle is installed on the corresponding fixed box. The fixed box is inclined on the side away from the folded tube, and the mating side of the fixed box and the atomizing nozzle is arc-shaped.

[0008] In one embodiment, a groove is provided on one side of the collar, and the side of the stop bar has the same arc shape as the groove.

[0009] In one embodiment, the interior of the delivery compartment is provided with an air guide tee and a liquid guide tee, the two ends of the liquid guide tee are respectively connected to two fixed boxes, a connecting pipe is provided between the air guide tee and the liquid guide tee, and a solenoid valve is provided on the outside of both the connecting pipe and the air guide tee.

[0010] In one embodiment, the delivery compartment has two cavities connected to the air tee, and two exhaust slots communicating with the cavities.

[0011] In one embodiment, the outer side of the delivery compartment is provided with a door, and two sealing strips are installed on one side of the door that can fit against the inclined side of the fixed box.

[0012] In one embodiment, a tray frame is slidably connected between the two fixed boxes, and two air guide grooves are formed inside the tray frame, with one end of the folded tube extending into the air guide grooves.

[0013] In one embodiment, a storage box is provided on the top of one of the delivery compartments. A T-shaped partition is provided inside the storage box. A micro air pump and a micro water pump are respectively provided on the outside of the T-shaped partition. The output ends of the micro air pump and the micro water pump are respectively connected to one end of the air guide tee and the liquid guide tee.

[0014] In one embodiment, one of the delivery compartments has a riser extending into the storage box, and a sterilization generator installed inside the storage box is located on the outside of the riser.

[0015] The aforementioned medical supply delivery robot with a sterile cabin self-disinfection function uses a conical column to drive the card box to rotate, which actively diffuses the disinfectant and improves the filling effect. In this process, a certain amount of gas is sprayed along the inside of the folded tube towards the collar, so that the gas is sprayed out along the flared groove and drives the atomized disinfectant to fly upward and outward, which locally counteracts the atomized disinfectant driven by the conical column, expands the filling range, prolongs the suspension time, ensures the disinfection effect, shortens the disinfection operation time, and reduces the amount of disinfectant used.

[0016] After the door is opened, sterile gas is sprayed out along the exhaust channel, forming a barrier air curtain at the door to reduce the entry of external dust and bacteria. At the same time, the tray is actively passed to the outside of the delivery cabin for easy access by the user, reducing the possibility of the user's hands coming into contact with the inside of the cabin and reducing the pressure of subsequent disinfection.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0035] The following is combined with Figures 1-10 This invention describes a medical supply delivery robot with a sterile cabin self-disinfection function.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 10 As shown, in one embodiment, a medical supply delivery robot with a sterile cabin self-disinfection function includes a delivery cabin 100 and a walking mechanism for driving its movement. There are two delivery cabins 100, and two sets of atomizing nozzles are provided inside the delivery cabins 100. It also includes a disinfection mechanism 200, which is located inside the delivery cabins 100 and is used to improve the disinfectant filling effect and suspension time. The disinfection mechanism 200 includes a rotatable conical column 210 and a collar 220 rotatably sleeved on its outer side. A set of card boxes is provided on the outer side of the conical column 210, and a germicidal lamp strip is provided inside the card boxes. A set of flared grooves 221 evenly distributed along the axis of the conical column 210 is opened inside the collar 220. A set of baffles 222 evenly distributed along the axis of the conical column 210 is provided on one side of the collar 220. The baffles 222 and the flared grooves 221 are staggered.

[0037] like Figure 3 and Figure 6 As shown, the disinfection mechanism 200 also includes two bends 230, which are asymmetrically arranged, with the ends of the bends 230 inclined upwards and facing the collar 220.

[0038] When disinfecting the delivery compartment 100, the disinfectant can be sprayed along the atomizing nozzle. Then, the speed-regulating motor on the conical column 210 is used to drive the conical column 210 to move the cartridge. During the rotation of the cartridge, the atomized disinfectant can be guided in multiple directions to improve the disinfectant coverage effect. This means that a small amount of disinfectant can be used for large-area disinfection, reducing the amount of disinfectant used. At the same time, the germicidal lamp can irradiate and sterilize in multiple areas when the cartridge moves, improving the sterilization efficiency.

[0039] At the same time, the gas is sprayed out along the folded tube 230, so that the gas is collected in the collar 220. After the gas is sprayed, the baffle 222 is subjected to force, which will drive the collar 220 to rotate on the conical column 210. During the rotation, the gas is discharged upward along the corresponding flared groove 221, which can blow the local disinfectant guided by the card box, improve its suspension time and diffusion effect.

[0040] It should be noted that the duration of gas introduction can be set according to actual use, so that the collar 220 moves intermittently, and the ends of the two bends 230 are respectively located on both sides of the axis of the collar 220. The gas ejected from the two bends 230 at different angles and in different directions acts on the corresponding baffles 222 in sequence, causing the collar 220 to rotate.

[0041] The walking mechanism used in this application includes a set of walking wheels in contact with the ground. These walking wheels are driven by servo motors. The specific driving method and internal structure are existing mature technologies and will not be described in detail here.

[0042] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the delivery compartment 100 has two fixed boxes 110 symmetrically arranged along the axis of the conical column 210. The atomizing nozzle is installed on the corresponding fixed box 110. The side of the fixed box 110 away from the folded tube 230 is inclined, and the docking side of the fixed box 110 and the atomizing nozzle is arc-shaped.

[0043] The atomizing nozzle is supported by a fixed box 110. Its arc side can expand the spraying range of the atomizing nozzle, and its inclined side can guide the sterile gas.

[0044] like Figure 10 As shown, a groove is provided on one side of the collar 220, and the side of the stop bar 222 has the same arc shape as the groove.

[0045] The groove design enhances the gas collection effect of the collar 220. Meanwhile, the interference gas can be discharged downward along the groove in a covering manner, causing the atomized disinfectant falling downward to be pressurized and move, making contact with the dead corner near the tray frame 160. A small amount of atomized disinfectant will also tumble upward after touching the bottom, improving the utilization rate of the disinfectant.

[0046] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the delivery compartment 100 is equipped with an air tee 130 and a liquid tee 140. The two ends of the liquid tee 140 are connected to two fixed boxes 110 respectively. A connecting pipe 131 is provided between the air tee 130 and the liquid tee 140. Solenoid valves are provided on the outside of both the connecting pipe 131 and the air tee 130.

[0047] Disinfectant is introduced into fixed box 110 through liquid guide tee 140, and then sprayed by pressure atomizing nozzle. At the same time, gas in gas guide tee 130 can be introduced into liquid guide tee 140 through connecting pipe 131. The suspension time of fine droplets will be extended due to the buoyancy of gas.

[0048] It should be noted that the air tee 130 and liquid tee 140 in the two delivery compartments 100 are connected by two C-shaped pipes. The C-shaped pipes and the outer side of the air tee 130 and liquid tee 140 in one of the delivery compartments 100 are each equipped with a corresponding electric control valve, which facilitates the separate control of the corresponding delivery compartments 100.

[0049] like Figure 4 and Figure 5 As shown, the delivery compartment 100 has two cavities that connect with the air tee 130, and the delivery compartment 100 has two exhaust slots 150 that communicate with the cavities.

[0050] When the hatch is opened, the exhaust duct 150 can spray gas along the inclined surface of the fixed box 110. The sterile gas forms a barrier air curtain at the hatch, reducing the entry of external dust and bacteria. The slightly inclined gas spraying method can directly squeeze the collected gas to the outside of the hatch, reducing the phenomenon of gas flowing back into the delivery compartment 100.

[0051] When the hatch is closed, the gas discharged from the exhaust duct 150 can be used to assist in the suspension of disinfectant, thereby improving the filling effect and suspension time of the disinfectant.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a door is provided on the outside of the delivery compartment 100, and two sealing strips 120 are installed on one side of the door that can fit against the inclined side of the fixed box 110; a pallet frame 160 is slidably connected between the two fixed boxes 110, and two air guide grooves are opened inside the pallet frame 160, with one end of the folded tube 230 extending into the air guide groove.

[0053] The pallet rack 160 is designed to limit the position of the pallet, reducing the occurrence of accidental pallet shifting and shaking, while improving the convenience of users picking up and placing the pallet. One side of the pallet rack 160 is equipped with an electric push rod for driving its movement.

[0054] With the addition of the air guide groove, when the hatch is closed, the sealing strip 120 will fit against the inclined side of the corresponding fixing box 110. At this time, the gas discharged from the exhaust groove 150 is blocked by the sealing strip 120, the fixing box 110 and the hatch. Subsequently, the gas can only be guided into the folding pipe 230 along the air guide groove to complete the gas delivery.

[0055] It should be noted that a human-machine interface control screen is installed on a delivery compartment 100. The human-machine interface control screen is equipped with a PLC controller, a camera for facial recognition, and a voice input module to perform facial decryption and voice control, reducing the occurrence of contact. In addition, a dual-axis motor is installed on the compartment door for automatic opening and closing.

[0056] like Figure 1 , Figure 2 and Figure 7 As shown, a storage box 170 is provided on the top of one of the delivery compartments 100. A T-shaped partition 171 is provided inside the storage box 170. A micro air pump 172 and a micro water pump 173 are respectively provided on the outside of the T-shaped partition 171. The output ends of the micro air pump 172 and the micro water pump 173 are respectively connected to one end of the air guide tee 130 and the liquid guide tee 140.

[0057] A T-shaped partition 171 is used to separate the disinfectant and the gas, and a micro air pump 172 and a micro water pump 173 are used to deliver the sterile gas and the disinfectant respectively.

[0058] It should be noted that the disinfectant used in this application is alcohol with a purity of 60% to 80%;

[0059] Furthermore, the storage box 170 is provided with an air inlet and a liquid injection hole on both sides, with a sealing plug inside the liquid injection hole and a filter inside the air inlet.

[0060] like Figure 7 and Figure 8As shown, one of the delivery compartments 100 has a riser 174 extending into the storage box 170, and a sterilization generator 175 installed inside the storage box 170 is provided on the outside of the riser 174.

[0061] The gas drawn into the storage box 170 is sterilized by a sterilization generator 175. At the same time, during the gas driving process, the interference gas in the delivery chamber 100 can be introduced into the storage box 170 through the riser 174 for the recycling of sterile gas, which is more energy-efficient and reduces the sterilization pressure of the sterilization generator 175.

[0062] It should be noted that the sterilization generator 175 is model NITTA FOGACT, and its size can be properly set in the storage box 170. Furthermore, the application and structure of this sterilization technology are existing mature technologies, and will not be elaborated here.

[0063] Working principle: The delivery robot is driven to the corresponding position by a walking mechanism. Then, the corresponding door is unlocked and opened by facial recognition and voice control. At this time, the micro air pump 172 operates, spraying sterile gas from the exhaust duct 150 to form a protective air curtain. Then, the electric push rod drives the tray frame 160 to move outward. The user can put the medical supplies along with the tray into it. Then, the door is closed by voice control. The delivery robot is driven to the corresponding position by the walking mechanism to complete the delivery of medical supplies. During the delivery process, disinfectant can be sprayed with atomizing nozzles.

[0064] It should be noted that this disinfection operation can be carried out in an empty cargo hold or during the transport of supplies; the specific method of use can be selected according to actual needs.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
